Kalshi has launched a $1 billion perfect bracket challenge tied to the NCAA Tournament, with financial backing from SIG Parametrics, LLC, the entity affiliated with Susquehanna International Group. The contest is free to enter, limited to 10 million total entries, and guarantees a $1 million prize to the highest-scoring participant if no perfect bracket is submitted.
How Kalshi’s $1 Billion Bracket Challenge Works
The Prize Structure
Kalshi is offering a top prize of $1 billion to any entrant who correctly predicts every game in the NCAA Tournament bracket. According to reports from Legal Sports Report and Covers.com, the promotion is structured so that the billion-dollar prize only pays out if someone achieves a genuinely perfect bracket [1].
If no participant submits a perfect bracket, the contest does not end without a winner. The top-scoring entry will receive a guaranteed $1 million prize, regardless of how many games that entry got wrong [1].
The financial backing for the promotion comes from SIG Parametrics, LLC, which is connected to Susquehanna International Group. This backing gives the prize structure institutional credibility rather than relying solely on Kalshi’s own balance sheet [1].
Entry Requirements and Limits
Participation in the Kalshi bracket challenge is free of charge. However, entrants must complete identity verification before their submission is accepted [1].
The total number of entries is capped at 10 million. Once that threshold is reached, no additional submissions will be accepted, making early entry a practical consideration for anyone interested in participating [1].
Who Can and Cannot Enter the Contest
State-Level Exclusions
Kalshi has explicitly excluded residents of two states from participating: New York and Florida. Anyone residing in either state at the time of entry is ineligible, regardless of whether they hold accounts on the Kalshi platform [1].
These exclusions are consistent with the regulatory complexity that prediction market operators frequently encounter at the state level in the United States. New York and Florida have historically maintained stricter oversight of contest and sweepstakes-style promotions, which likely informs Kalshi’s decision to exclude those residents [1].
Identity Verification Requirement
All eligible participants must complete identity verification to enter. This requirement is standard for regulated financial and prediction market platforms and serves to prevent duplicate entries and ensure compliance with applicable rules [1].
The combination of a free entry model and a mandatory identity check positions the contest as a sweepstakes-style promotion rather than a paid gambling product, which has direct implications for how it is regulated across different jurisdictions [1].
Contest Rules at a Glance

| Guaranteed Prize | $1 million (top-scoring entry) |
| Entry Cost | Free |
| Entry Cap | 10 million entries |

| Financial Backer | SIG Parametrics, LLC (Susquehanna International Group) |
The structure mirrors large-scale promotional contests that have appeared in other sports contexts, most notably the Warren Buffett-backed perfect bracket challenge that drew widespread attention in prior years. Kalshi’s version raises the stakes significantly with a $1 billion headline figure [1].
The 10 million entry cap is a meaningful constraint. With tens of millions of Americans filling out NCAA brackets each March, the cap means a significant portion of interested participants may be locked out if the contest gains rapid traction [1].
Prediction Markets, Sports Betting, and the Gambling Connection
Kalshi operates as a regulated prediction market platform, which places it in a distinct but adjacent space to traditional sports betting and crypto gambling. The NCAA bracket challenge is structured as a free-to-enter sweepstakes rather than a wagered contest, but it draws on the same audience that engages with March Madness prediction markets and sports outcome betting [1].
For readers familiar with crypto casinos and prediction-based wagering, the Kalshi promotion reflects a broader trend of regulated platforms using high-profile prize structures to attract users who might otherwise engage with offshore or crypto-native betting products. The identity verification requirement and state-level exclusions signal that Kalshi is operating within a compliance framework that distinguishes it from unregulated alternatives [1].

The Bottom Line

The free entry model, institutional financial backing from SIG Parametrics, LLC, and a guaranteed $1 million fallback prize make it a structurally credible promotion rather than a purely theoretical offer [1].
The exclusion of New York and Florida residents and the 10 million entry cap are the two most significant practical constraints for potential participants. Anyone eligible and interested should be aware that the entry cap could close the contest before the tournament begins if demand is high [1].
For the prediction market and sports betting community, this promotion signals that regulated platforms are willing to deploy major prize structures to compete for audience attention during one of the most-watched sporting events in the United States.
